3 If you feel unwell, seek medical advice (show the label if possible). NU-22B (R-422B) Safety Data Sheetaccording to Federal Register / Vol. 77, No. 58 / Monday, March 26, 2012 / Rules and Regulations 08/30/16 EN (English US) 2/7 Inhalation: Remove to fresh air and keep at rest in a position comfortable for breathing. Obtain medical attention if breathing difficulty persists. Skin Contact: Rinse immediately with plenty of water. Obtain medical attention if irritation develops or persists. Eye Contact: Rinse cautiously with water for at least 15 minutes. Remove contact lenses, if present and easy to do. Continue rinsing. Obtain medical attention. Ingestion: Do NOT induce vomiting. Rinse mouth.

4 Immediately call a POISON CENTER or doctor/physician. Most Important Symptoms and Effects Both Acute and Delayed General: Vapors are heavier than air and may cause asphyxia by reduction of the oxygen content. Inhalation: May cause respiratory irritation. Skin Contact: May cause skin irritation. Liquid contact may cause frostbite. Eye Contact: May cause eye irritation. Ingestion: Ingestion is likely to be harmful or have adverse effects. Chronic Symptoms: None expected under normal conditions of use. Indication of Any Immediate Medical Attention and Special Treatment Needed If you feel unwell, seek medical advice (show the label where possible). SECTION 5: FIRE-FIGHTING MEASURES Extinguishing Media Special Hazards Arising From the Substance or Mixture Advice for Firefighters Precautionary Measures Fire: Exercise caution when fighting any chemical fire.

5 Firefighting Instructions: Use water spray or fog for cooling exposed containers. Protection During Firefighting: Do not enter fire area without proper protective equipment, including respiratory protection. Hazardous Combustion Products: Carbon oxides (CO, CO2). Halogenated hydrocarbons. Hydrogen Fluoride (HF). Reference to Other Sections Refer to section 9 for flammability properties. SECTION 6: ACCIDENTAL RELEASE MEASURES Personal Precautions, Protective Equipment and Emergency Procedures General Measures: Avoid all contact with skin, eyes, or clothing. Avoid breathing vapors. For Non-Emergency Personnel Protective Equipment: Use appropriate personal protection equipment (PPE).

6 Emergency Procedures: Evacuate unnecessary personnel. For Emergency Personnel Protective Equipment: Equip cleanup crew with proper protection. Emergency Procedures: Stop leak if safe to do so. Ventilate area. Environmental Precautions Avoid release to the environment. Methods and Material for Containment and Cleaning Up For Containment: Ventilate area. Methods for Cleaning Up: Isolate area until gas has dispersed. Reference to Other Sections See Heading 8. Exposure controls and personal protection. Suitable Extinguishing Media: Use extinguishing media appropriate for surrounding fire. Unsuitable Extinguishing Media: None known. Fire Hazard: NU-22B is not flammable at atmospheric pressure and in air at temperatures up to 100 C (212 F).

7 NU-22B should not exist with air/excess oxygen at elevated pressures and high temperatures. NU-22B can become combustible with high concentrations of air at elevated pressure and/or temperature and in the presence of an ignition source. Theis substance can also become combustible in an oxygen enriched environment (oxygen concentrations greater tha that in air). For example, do not mix NU-22B with air under pressure for leak detection purposes. Explosion Hazard: Product is not explosive. Heat may build pressure, rupturing closed containers, spreading fire and increasing risk of burns and injuries. Reactivity: Hazardous reactions will not occur under normal conditions.
